IMPROVEMENT IN SEAL-LOCKS.

Specication forming part of Letters Patent No. 122,459, dated January 2,1872.

or analogous material, which must be broken before access can be had tothe spring-catch to separate the parts.

The details 'of construction are hereinafter described.

In thedrawing, Figure' l is a perspective view ofthe lock. Fig. 2 is alongitudinal section of the same.

A represents a rigid cross-bar, formed at its ends with sockets a a! toreceive the ends b b of the bow B. In the longer and larger end I) ofthebow is formed a seat for the seal S,which,

when the parts are locked together, is exposed through an opening in theface of the bar, but cannot escape therethrough in a whole condition.The locking is effect-ed by the springcatch O, which may preferablyconsist of a pin pressed forward by a spring, D 5 but this form of catchis not new in itself, and I do not desire to limit myself to any specialshape therefor. The said pin engages in a hole provided for it in thebow B in such position as to be covered by the seal S. The end B of thebow being elongated, as shown, may be provided with one or moreadditional openings below the cross-bar to receive lead seals T foradditional security.

I apply the invention in locking the doors of a frei ght-car, forexample, which is one use for which the invention is well adapted. Thehasp ofthe door is passed over the staple in customary manner, and thebow B, with the seal S applied, is then passed through the staple andits ends are inserted in the sockets of the bar A, whereit is securelyheld bythe springcatch C. In order to release the parts it will now beneedful to break the seal S, after which a pointed instrument is pressedupon the end of the catch O, forcingit back whilel the bow B iswithdrawn.

I claim as my invention'- The seal-lock herein described, consisting ofthe bow B b b', cross-bar or socket piece A a a', and spring-catch O,all constructed and adapted for use in connection with a seal, S, ofglass or analogous material, in the manner andfor the purposesspecified. l
